Laying Low in the Servants' Quarters, I Turned Scrap into Immortal Artifacts with Critical Hits

Chu Xuan is the lowliest odd-job disciple in the Tai Xuan Sect. He has to put up with the steward skimming his pay, while also facing the danger of being used as cannon fodder. Then one day, after a senior sister from the Hehuan Peak drains him nearly to death, the treasure basin his parents left him finally appears. “Put in a low-grade Qi-Gathering Pill, trigger a hundredfold critical hit, and get a top-grade Nine-Pattern Immortal Pill!” “Put in an incomplete sword manual, trigger a thousandfold critical hit, and get the Heaven-Rank Great Wilderness Sword Art!” “Put in a weed, trigger a ten-thousandfold critical hit, and get a Nine-Leaf Immortality Divine Herb!” Years later, the demon race invades, the immortal realm collapses, and countless Immortal Emperors await death in despair. Chu Xuan walks out holding his battered basin and casually pours out billions of top-grade immortal weapons. “Don’t panic. Everyone pick one and hack them to death!”
